You will take problems from first customer conversation through to production, usually within weeks rather than quarters. That means building the reasoning and guardrails that let an agent act reliably, wiring it into the systems customers already run, and shipping the product surfaces people use every day.

• What you'll actually be doing:Building AI agents and the workflows behind them
• Integrating with real enterprise systems and data, so agents can act without anyone ripping out their existing tools
• Full stack ownership - APIs, services, and the front end customers touch
• Working directly with founders and customers.

Stack: React/Next.js, TypeScript, NestJS, PostgreSQL, AWS.

What we're looking for:2-4 years professional experience, ideally shipping product in a small or fast-moving teamStrong fundamentals - you can own a problem end to end without a detailed playbookCurious, comfortable with ambiguity, happy figuring things out rather than waiting to be told

This is early-stage: priorities move fast, some problems have no established answer, and what you build has real visibility in the company's direction.

In person - DublinIn practice that's around four days a week, with flexibility if you need to work from home occasionally. I know this won't be everyone's cup of tea, but the team genuinely values being in the room together, and the right person wants that too rather than just tolerating it - it's not a rigid five-day mandate, it's a culture thing.

The Prism team builds the systems that turn Elastic Security's raw data into a trustworthy picture of the users, hosts, and services in a customer's environment. We power the Entity Store, entity risk scoring, entity resolution, and the data maintainers that analysts rely on to understand who did what, what's risky, and what to investigate next. We build features that have to work at scale, and we care deeply about correctness and performance.

As a senior engineer, you will lead technical work across this area. You'll partner with product, design, and engineering to turn hard, ambiguous problems into reliable, performant systems that ship to real security teams.

• We're a distributed team — we work across time zones and collaborate in GitHub, Slack, design reviews, and code review
